Signal processing device, signal processing method, and non-transitory computer-readable storage medium storing a program

A signal processing method comprising:

• acquiring a time-series signal by a signal acquisition unit,
• detecting, by a detection unit, a signal of an interval including an event indicated by an event label as an event signal from the time-series signal,
• generating, by a first AQA processing unit, an answer sentence to a question sentence based on the time-series signal, interval information indicating a relationship between the time-series signal and the event signal, the event label, and the question sentence related to the event label.

A non-transitory computer-readable storage medium storing a program that causes a processor to execute,

• causing a signal acquisition unit to acquire a time-series signal,
• causing a detection unit to detect a signal of an interval including an event indicated by an event label as an event signal from the time-series signal,
• causing a first AQA processing unit to generate an answer sentence to a question sentence on the basis of the time-series signal, interval information indicating a relationship between the time-series signal and the event signal, the event label, and the question sentence related to the event label.
